| 摘 要： | 针对二次雷达系统中天线旁瓣使目标在雷达显示器上形成多点应答现象，提出了4种多点应答问题解决办法：在询问机通过和波束发射询问信号的同时通过另一天线发射抑制波束实现发射旁瓣抑制：通过比较询问机和差波束接收信号幅度实现接收旁瓣抑制；通过调节发射机功率开关控制询问机功率实现功率控制旁瓣抑制；通过控制接收机灵敏度实现灵敏度控制旁瓣抑制．

| Abstract: | Aiming at antenna side lobe make target to form multipoint response on radar display in secondary radar system, 4 kinds of resolving method of multipoint response were presented. When transponder transmitted enquiry signal with sum wave beam, transmitting side lobe restrain was realized with other antenna transmitted restrain wave beam at one time. Receiving side lobe restrain was realized by compared the receiving signal extent for sum and difference beams of transponder. The side lobe restrain of power control was realized by regulating power switch of transmitter to control the power of transponder. The side lobe restrain of sensitivity control was realized by controlling sensitivity of receiver. |
